(No model.)Patented in France October 15,1888, 110,198,542 in Belgium June 14,1889,1To. 86,638; in $pai11 October 26,1889,N0.10,13'7; in SwitzerlandOctober 26,1889,No,1,524-.: in England October 31, 1889, No 17,295; inItaly November 19, 1889, No. 26,508; in Germany December 10. 1889, No.54,179, and in Austria-Hungary February 17, 1890.

To aZZ whom it may concern.-

Be it known that we, PAUL NIEL and ALEX- ANDRINE JANIOT, citizens of theFrench Republic, residing at Paris, France, have invented new and usefulImprovements in Gas- Motors, (for which we have obtained LettersPatentin Great Britain October 31, 1889, No. 17,295; in Belgium June 14,1889, No. 86,638; in Germany December 10, 1889, No. 54,179; in Austria-llungary February 17, 1890, no number, in France October 15, 1888, No.198,542; in Spain October 20, 1889, No. 10,137; in Italy November 19,1889, No. 26,508, and in Switzerland October 26, 1889, No. 1,524,) ofwhich the following is a full, clear, and exact description.

Our invention has for its object to improve gas or other hydrocarburetmotors wherein the cycle is completed with two revolutions of thedriving-shaft; and its chief features are improvements of thedistribution, the regulation by means of the arrangements andcombinations hereinafter described, reference being had to the drawingswhich make a part of this specification, and wherein similar lettersrefer to similar parts throughout the several views.

Figure 1 illustrates the cylinder in elevation. cylinder andappurtenances. transverse section of the same. a detail view of theregulator.

A is the cylinder with a jacket of water, and B the piston connected bya rod with the crank. (Not shown on the drawings.)

On the driving-shaft is keyed a helicoidal pinion gearing with a wheelhaving twice the number of teeth and fixed on the end of the axle D,which thus receives a rotary motion and will make one revolution forevery two revolutions of the crank. A conical gearing can of course alsobe employed. The axleD carries along in its rotary motion the conicalcore of a cock E, the eccentric F, and the cam G. The Wall or valve-seatsurrounding the conical distributing-cock is provided with the apertureH for the compression-chamber I of the cylinder, and the aperture .1,corre- Fig. 0 is a Fig. 4 shows Fig. 2 shows a horizontal section of thesponding with the inlet of the mixture of air, which is fed by the pipeK, and of gas, which is ad mitted by the valve L, opening on theadmission gas-pipe M. It is furthermore provided with the small aperturen, Fig. 3, corresponding with the tube 0,'closed at its upper end, whichserves for the ignition, and is kept incandescent by the Bunsen burnerc.

The conical core of the distributer is provided with a hole N, whichputs into communication the apertures H and J at the moment of theaspiration with the small hole a, Fig. 3, which brings intocommunication the aperture n with the aperture H at the moment of theignition and with the hole e, ending in a cavity arranged in the core,and which at the moment of the compression and the explosion brings thecylinder into communication with a small chamber arranged in the upperend of the core in the manner and for the purpose hereinafter described.The upper end of the core is inclosed in a narrow cham- 7o ber and isprovided with a cylindrical cap,

' wherein the cover (Z is screwed and strongly presses the edges of avery flexible metallic plate i 1', which is fixed in its middle on thehead of the core by means of a hollow screw, which corresponds with thehole 6. The screw N is adjusted so as to abut the back center of saidcap and merely keeps the core in its casingwithoutexercisinganypressure.When the compression and the ignition occur, the interior pressure willpenetrate in the space provided between the lid (Z of the cap and theflexible plate. The pressure then acts upon this plate, and by means ofan arrangement of tongues provided in the cap the core is pushed down inits casing, and thus the tightenin g assured at the moment of greatestpressure in the cylinder. The screw N is mounted on a link N which canbe rotated on one of its adjusting-bolts, and it is consequently onsufficient to loosen and rotate this link for the purpose of taking thecore out of its casing and cleaning it.

As shown in Fig. 3, the exhaust is made through an aperturecommunicating with the 5 compression-chamber and is closed by meanscharge depends on the dimensions of the aperture of the cock.

It will be remarked that the chamber of equilibrium of our conical cockand its metallic membrane are placed and directly acted upon in theupper part of the conical plug. Furthermore, that this plug is placedhorizontally and in line with and in combination with the axle, which isdirectly acted upon by the driving-shaft without any intermediate partof transmission.

The regulator, Fig. 4, is composed of the lever T, pivoted at its end V,and which receives by the medium of the eccentric F and its collar U andarm U, pivoted in the middle of the lever, an upward anddownwardoscillating movement. At the free end of this lever is pivoted anothertwo-armed lever, one arm of which abuts at every ascending movementunder an adjusting-screw g, while the other arm is provided with a rigidmetallic blade h. To the center piece of these two levers is also fixeda flexible steelblade r, the free end of which is provided with ametallic mass m, which at every oscillation strikes upward against astop and downward on the head of an adjusting-screwy, deadening thevibration. 7

When the machine is running at its regular rate of speed, the end of theblade h will open the gas-valve L while pushing on the projection at theend of the lever Z, which rests on the stem of said valve exactly at themoment of the aspiration; but if the machine should run at a greaterspeed, and consequently theleverT be moved faster, the springblade 1'has no time to straighten the blade h Y quickly enough, which latterwill thus fail to strike the projection, and consequently pass the endof the lever Z without moving the valve. The machine will consequentlybe deprived of gas, and thus come back to its regular rate of speed.

The air-admission pipe K, Fig. 1, and the gas admission pipe, Fig. 2,carry each a valve provided with hand and dial, which allow ofregulating, after some experiments, the relative admission of air andgas to obtain the most suitable proportion. The air and gas flowing outof these pipes pass, as shown in Figs. 2 and 3, through several smallholes, which assure a thorough mixture.

Having now fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. In a gas or other hydrocarburet motor, the combination of a conicalhorizontal cock, as herein described, provided at its upper end with theequilibrium-chamber, wherein the gas directly efiects its pressure atthe moment of the compression and the explosion, and the driving-shaftconnected directly with said cock, substantially as set forth.

2. In a gas-engine, the regulator formed by the combination of a leveroscillating by the operation of the engine, and which in its loweringmotion opens the gas-admission valve,

. and an elastic weighted steel bladeconnected with the lever which atan increase of the speed prevents the opening of said valve andconsequently decreases the speed of the engine, substantially as setforth.

In witness whereof we have hereunto set our hands in presence of twowitnesses.
